Subject: cfg80211: remove racy beacon_interval assignment
X-Git-Tag: v3.14-rc8~3^2~21^2^2~6^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bc00a91d627026f08abf69bf5d0015499dd30c2a;p=platform%2Fkernel%2Flinux-stable.git

cfg80211: remove racy beacon_interval assignment

In case of AP mode, the beacon interval is already reset to
zero inside cfg80211_stop_ap(), and in the other modes it
isn't relevant. Remove the assignment to remove a potential
race since the assignment isn't properly locked.
